Is this really malware?

Hi after an update to S&D I get a report of Win32.SonyAgent.NFP I can't find any info about this and what it does/how it does it. It seems to be new to Spybot scans and others. Normally geek forums etc have a lot about new malware so Iam puzzled.

It consists of (on mine anyway) an exe, 2 dlls and 2 reg entries
C:\WINDOWS\system 32\drivers\npf.sys
C:\WINDOWS\system 32\Packet.dll
C:\WINDOWS\system 32\wpcap.dll
then the reg entries in
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\NPF
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Services\NPF

It rebuilds at next boot after S&D removes it (after removal npf.sys stays, I can't find wpcap.dll and Packet .dll but there is always a Packet.dll_old so that gets reborn at boot I guess)

OK so also why I am puzzled is that after trying to replace the drivers I wound up with a non-booter. I do keep a clone of "C" unplugged and redone every few weeks when everything is running OK. I swapped HDs and there is the SonyAgent (but that was from 5 weeks ago and Spybot, Malwarebytes et al never found it then. it must have been around a while. Also the only people who seem to be connected with it are CACE Technologies inc. who LOOK legit. Hmmm! any more information would be appreciated.

Hello,

this is a rookie false positive. Sorry for the inconvenience. And shame on us for not noticing it before it went public.
These are actually network capture drivers for instance used by Wireshark.
This will be fixed with the next detection update coming up tomorrow Wednesday 2013-04-24.

Many thanks Yodama for a prompt reply and for putting my processor at rest on this!

Phew, I just got this too. Good to know it's just a false positive! :)
